I've replaced the cmos battery but the time/date aren't being held when the laptop is powered down or put in sleep. Don't know if this is related but it started happening when I let MS install Silverlight and that installation failed.

I talked to HP and they thought it was the cmos battery (laptop JUST went out of warranty! Of course). So I got the battery and installed it... nada (don't panic, I do have an IT background and have built servers from the ground up.)

Driving me crazy!! Help

Couple things...
1) there is malware that does this , so just for fun.. download/run Malwarebytes

2) there is a battery called an RTC battery. It's a lithium battery just for keeping the clock running... I don't know anything more than that about RTC's

Thanks, I will run the malware removal tool and see if that helps. The RTC battery is the one that I replaced... nothing there.

Thanks again for replying

My suggestion is doing a extensive cleanup including the registry and if that don't work then it could be a minor bios setting boot into the bios and load setup defaults and see if that works

Thanks, nothing I have tried so far has worked so this is definitely worth a shot! I set the defaults and will see what happens... Jayne

I have this same issue with my Dell laptop.

I have this same issue with my Dell laptop.

I don't know if it's hardware or software issue. Have tried everything software related that I can find, next step is customer support with HP... hopefully it's not a major hardware thing, the laptop is only 18 mo. Old! And out of warranty!

Good luck

Have you removed or touched the clear cmos jumper maybe you have a jumper out of place near the cmos that every time power is off it resets check the jumpers

Not familiar with that... I've worked on a lot of servers, never a laptop... I'll power down and see what I can find... thanks

Powered down, looked inside and it would appear that I don't know what I'm looking for! <<Grin>>

I unplugged the cmos battery, I don't see jumpers of any kind... hmmm, maybe that's the problem?

Try a new battery

Thanks
